Crab Plover (Dromas ardeola) is the only member of this family. The bird resembles a long-limbed plover, with a black-and-white plumage and partially webbed toes. Its heavy bill is adapted to its diet of crabs, and the species is unique among waders in nesting burrows and using ground warmth to help incubate its eggs; as a consequence its young are, unlike all other waders, helpless after hatching and require feeding. Crab Plovers breed in the Arabian Sea and Persian Gulf and disperse around the coasts of the Indian Ocean outside the breeding season.
